"Symbian anti-virus specialist SimWorks announced today that it has identified the first threat able to so severely disrupt the functioning of a Symbian phone that it can no longer be used to make phone calls. Previously identified threats, such as the Skulls trojans, have affected only the higher level functions of a device, not it's ability to make calls".

Microsoft Downplays Office Encryption Weakness
security researcher has issued an alert for a "serious security flaw" in the way document encryption is implemented in Microsoft's Word and Excel products, warning that a widely-used encryption algorithm is being misused by the software giant. However, Microsoft officials are downplaying the threat, insisting that the reported flaw poses a very low threat for users of the two popular word processing programs.
Hongjun Wu, a researcher at the Institute for Infocomm Research in Singapore, said Microsoft is misusing the RC4 (Rivest Cipher 4) algorithm that is licensed from RSA Data Security.
However, a spokesperson for Microsoft told eWEEK.com that an early investigation of Wu's findings showed that the issue did not present a major threat. "In some cases, an attacker may be able to read the contents of an encrypted file if multiple versions of that file are available to the attacker," the spokesperson acknowledged.
